Newbie - Stain removal via ascorbic acid

[aylad]

yes, in a 25K gallon pool, each 6 cups of 6% bleach will raise your chlorine by approximately 1 ppm.

So here's my update:
I added two quarts of muriatic acid last night, filter is on 24/7. As of this morning the pool went from crystal clear to now cloudy white (can't see the bottom). And my current readings are:

FAC: 0
TAC: 0
pH: 7.2
Alk: 110

In hind-sight prior after a full 24 hrs. of my initial 5 lbs. of the ascorbic acid, the over all stain was reduced by about 50%...meaning not as dark. I'm wondering if I should have just did another ascorbic acid treatment?

You need to get some chlorine in there or its gonna be cloudy AND green!

I've added 182 oz of bleach over the last 24 hours but still showing 0 on my chlorine. I also put in some a little polyquat 60.

Right now I wanna get balanced and clear ,,,then I think I'll do another 5 lbs. of the ascorbic acid treatment.

What a tangled circle this all is.

Please go back and re-read Ben's post above and follow his directions carefully. He knows what he is talking about and by following his advice to the letter, you'll have the best chance at getting this problem taken care of successfully.

Per Ben's directions above, you need to be chlorinating with trichlor pucks which will help the iron to fall out into your filter. If the ones you bought are the dual-action ones with copper, don't use them. Go and buy some plain trichlor pucks. (Bleach will add chlorine but will not cause the iron to fall out into your filter.)

Good luck and keep us posted how it is progressing.

The ascorbic acid and polyquat both eat chlorine, which is why you're having a tough time keeping a chlorine residual. When you asked about putting bleach into the pool to bump up chlorine, you can certainly do so, if you're trying to chlorinate the pool. However, one of the things Ben is trying to accomplish by having you put the trichlor puck into the skimmer is to create a high dose of chlorine that the water has to pass through on its way to the filter, which causes the metals to fall out and be trapped on the filter. Bleach won't work for this purpose, because the dose goes straight through the filter and back out to the pool.

Janet,,thanks for the insight (makes perfect sense). I pick up the correct trichlor pucks and I'll follow the rest of Bens direction.

I just became paranoid when the water turned so cloudy after the muriatic acid application...(was that suppose to happen?). (when might I expect it to clear up?)
